Which Wich, a new sandwich shop at 4300 Wilson Blvd in Ballston, is planning to open its doors on Tuesday.

The store is the chain’s first in the D.C. area, and the third fourth in Virginia. Which Wich touts its selection, with over 50 sandwich varieties and more than 60 toppings — offering some 56 trillion possible combinations. There’s also a Coke Freestyle machine at the store, with more than 100 drink and flavor combinations.

“The eatery offers a wide variety of options, from flavorful BLTs to offbeat offerings like the honey-banana-peanut butter-bacon-laden Elvis Wich,” said a press release. “Those seeking a healthy spin can choose from over 30 Wiches and Bowlwiches that contain fewer than 400 calories and 6 grams of fat.”

The store officially opens on Tuesday, May 21, according to the press release. It held a “special VIP Preview Party” on Wednesday night.

Which Wich will be open Monday through Friday from 7:00 a.m. to 10:00 p.m., and Saturday through Sunday from 10:30 a.m. to 9:00 p.m.
